Exidia
''Exidia'' is a genus of fungi in the family Auriculariaceae. The species are saprotrophic, occurring in attached or recently fallen dead wood, and produce gelatinous basidiocarps (fruit bodies). The fruit bodies are diverse, pustular, lobed, button-shaped or cup-shaped. Several species, including the type species ''Exidia glandulosa'', have sterile pegs or pimples on their spore-bearing surface. The genus has a cosmopolitan distribution and around 20 species are currently recognized worldwide. Initial molecular research indicates the genus is artificial. Taxonomy ''Exidia'' species were originally placed in the genus ''Tremella'' along with many other gelatinous fungi. The genus ''Exidia'' was separated from ''Tremella'' by Fries in 1822, based mainly on fruit body shape. Fries initially included species now assigned to ''Auricularia'' within the genus. Recent molecular research has indicated that ''Exidia'' as currently circumscribed is an artificial grouping, the species not b ...

Exidia Glandulosa
''Exidia glandulosa'' (common names black witches' butter, black jelly roll, or warty jelly fungus) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The fruit bodies are up to wide, shiny, black and blister-like, and grow singly or in clusters. Its occurrence elsewhere is uncertain because of confusion with the related species, ''Exidia nigricans''. Taxonomy The species was originally described from France as ''Tremella glandulosa'' by Bulliard in 1789. It was subsequently placed in ''Exidia'' by Fries in 1822. Fries, however, modified Bulliard's species concept to include a second, effused, coalescing species—the name ''Exidia glandulosa'' serving for both. This combined concept was used until Neuhoff separated the two species in 1936. Unfortunately, Neuhoff gave the name ''Exidia glandulosa'' to the effused species, adopting the name ''Exidia truncata'' for Bulliard's origina ...

Exidia Nigricans
''Exidia nigricans'' (common name Witches' butter) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species throughout the northern hemisphere, typically growing on dead attached branches of broadleaf trees. It has been much confused with ''Exidia glandulosa''. Taxonomy The species was originally described from England as ''Tremella nigricans'' by William Withering, Withering in 1776, based on a phrase name published by Dillenius in 1741. It was subsequently considered a synonym of ''Exidia glandulosa'', until Marinus Anton Donk, Donk revised species concepts in 1966 and placed it in synonymy with ''Exidia plana''. Changes in the starting point for fungal nomenclature has made ''Exidia plana'' illegitimate, however, leaving ''Exidia nigricans'' as the earliest name for the species.Roberts, P. (2009). ''Exidia nigricans'': a new and legitimate name for ''Exidia plana''. ''Mycotaxon'' 109: 219–220. Molecular research has shown that ''Exidia glandulo ...

Exidia Recisa
''Exidia recisa'' (common name willow brain or amber jelly roll) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species throughout the northern hemisphere, typically growing on dead attached twigs and branches of willow and other broadleaf trees. Taxonomy The species was originally found growing on willow in Germany and was described in 1813 by L.P.F. Ditmar as ''Tremella recisa''. It was transferred to the genus ''Exidia'' by Fries in 1822. ''Tremella salicum'' (the epithet means "of willow") has long been considered a synonym. The epithet "recisa" means "cut-off", with reference to the shape of the fruit bodies. Description ''Exidia recisa'' forms orange-brown or amber, gelatinous fruit bodies that are firm and shallowly conical at first, becoming lax and pendulous with age, and around 2.5 cm (1 in) across. The fruit bodies typically grow gregariously, but do not normally coalesce. The upper, spore-bearing surface is smooth and shiny ...
